vocal acoustic shield

Most panels and shields list thicknesses around 2 inches for fiberglass and foam products; some wood-slatted panels are about 1 inch thick. At least one fiberglass option lists an NRC as high as 0.95. Exact thickness and NRC vary by model and manufacturer.

Many isolation shields are designed to be portable and collapsible. Listings describe foldable or collapsible panel designs, zipper assemblies for packing, and overall lightweight construction to make transport and storage easier.

Mobile vocal booths typically enclose the vocalist almost entirely to greatly reduce room reflections. Isolation shields use folding panels lined with foam that surround the microphone to mitigate ambient noise and echoes without fully enclosing the performer.

Common materials include fiberglass, high-density or EVA foam, polyester felt backing, and wood veneer over MDF slats.
